Abstract

Embodiments disclosed herein are directed towards systems and methods for electric current leakage detection in a land seismic system. Embodiments may include generating at least one test signal using a digital to analog converter 'DAC' circuitry, wherein the DAC circuitry includes an output operatively connected to earth ground. Embodiments may further include alternately grounding a positive path to an analog to digital converter 'ADC' circuitry during a first time window and a negative path to the analog to digital converter during a second time window while measuring an ADC signal. Embodiments may also include determining an average amplitude of the first time window and the second time window and determining a leakage resistance based upon, at least in part, the average amplitude of the first time window and the second time window.
